In addition to CD4+Foxp3+ regulatory T cells, several subsets of Foxp3- regulatory T cells, such as T helper 3 (Th3) cells and type 1 regulatory T (Tr1) cells, have been described in mice and human. Accumulating evidence shows that na?ve B cells contribute to tolerance and are able to promote regulatory T cell differentiation. Na?ve B cells can convert CD4+CD25- T cells into CD25+Foxp3- regulatory T cells, named Treg-of-B cells by our group. Treg-of-B cells express LAG3, ICOS, GITR, OX40, PD1, and CTLA4 and secrete IL-10. Intriguingly, B-T cell-cell contact but not IL-10 is essential for Treg-of-B cells induction. Moreover, Treg-of-B cells possess both IL-10-dependent and IL-10-independent inhibitory functions. Treg-of-B cells exert suppressive activities in antigen-specific and non-antigen-specific manners in vitro and in vivo. Here, we review the phenotype and function of Foxp3+ regulatory T cells, Th3 cells, Tr1 cells, and Treg-of-B cells. ? 2017 The Author(s). |
